About Vial Guide
A free peptide reference that shows where every number comes from.
What it is
Vial Guide covers 42 peptides and 6 blends: what each one is, how it’s dosed and cycled, how to mix it, and what the evidence behind it looks like. The calculator turns a vial, a volume of water and a dose into syringe units, and works out how many vials a full run takes.
Every dose carries a label. Label means an approved product’s prescribing information, Trial means a published human study, and Community means commonly reported but not established. Each compound page also shows its approval and sport status, its key human studies and a datasheet.
Who makes it
Vial Guide is an independent site written and maintained by the Vial Guide editors. Pages are researched from prescribing information, published studies and regulators’ own documents, and each page shows when it was last reviewed.
How it’s paid for
Vial Guide is free to use and has no ads, sponsors, accounts or affiliate links. It doesn’t sell peptides, and it doesn’t link to sellers or to any other site. Sources are listed as citations you can look up yourself.
What it isn’t
It isn’t medical advice, and it doesn’t recommend doses. Many compounds here aren’t approved for human use. Read the disclaimer before using any number on the site.
